Question

Which of the following in not a linear equation in one variable?
Answer=(a) 33z+5 ( b) 33(x+y) (c) 33x+5 (d) 33+5

Answer 1

Answer:

I think so 33(x-y) is the answer

Answer 2

(b) 33 (x + y), (d) 33 + 5

33 (x + y) and 33 + 5 are not linear expressions in one variable.

Explanation:

If an equation or expression has only one variable with power 1, say x, y, etc., is called an equation or expression in one variable.

• (a) Here the expression is 33z + 5. Since there is only one variable z, the expression is linear in one variable.

• (b) Here the expression is 33 (x + y). There are two variables, x and y. So it certainly is linear but with two variables.

• (c) Here the expression is 33x + 5. Since there is only one variable x, the expression is linear in one variable.

• (d) Here the expression is 33 + 5. It has no variable at all.
